On the morning of July 18, 2014, 41-year-old Florida State law professor Dan Markel dropped his boys off at preschool, hit the gym, and headed home to his quiet, tree-canopied neighborhood.

Crime solving for me is more complex than the challenge of the hunt, or the process of piecing together a scientific puzzle. The thought of good people suffering drives me to the point of obsession.
